PIANO DAMP-ABSORBER.

Application filed November 18, 1912, Serial No. 732,115.

Specification of Letters Patent.

To all "whom it may concern:

Be it known that we, JAMES W. Co-RLIss and J AMES VVHARMBY, citizens ofthe United States, residing at Lakeland, in the county of Polk and Stateof Florida, have invented certain new and useful Improvements in PianoDamp-Absorbers, of which the following is a specification,referencebeing had therein to the accompanying drawing.

This invention relates to piano damp absorbers, and has for its objectthe production of an eflicient absorber for absorbing dampness in pianosfor preventing warping of the different portions of the mechanism andalso preventing the sticking of the keys.

Another object of this invention is the production of an eflicientcasing for a lamp which may be readily disassembled in order to placethe lamp therein and remove the lamp therefrom.

With these and other objects in view, the invention consists in generalof certain combinations and arrangements of parts as will be hereinafterfully described, illustrated in the accompanying drawings, andspecifically claimed.

In the drawings, Figure l is a central longitudinal section of theheater. Fig. 2 is a front view thereof. Fig. 3 is a side View of theheater.

By referring to the drawings, it willbe seen that 1 designates a basewhich constitutes a lamp supporter, and this base is provided with alaterally extending rim 2 upon its lower end. A plurality of punchedtongues 3 are formed from the side of the base 1, and these tongues 3support upon their upper ends the lamp 1. A plurality of lugs 5 aresupported upon the outer face of the base 1, and these lugs 5 constitutea support for the main heating flue 6. The outer ends of the lugs 5 arebent over as indicated at 7 to constitute an upper rolled edge for thebase 1. The heating flue 6 is provided near its lower end with aplurality of ventilating apertures 8, and also an enlarged opening 9 forfacilitating the lighting of the lamp and for admitting a large amountof air. Other ventilating apertures 10 are also employed in the heatingflue 6.

A pair of laterally extending flue members 11 are carried by the flue 6and these laterally extending flue members 11 are provided along theirupper ends with a plurality of ventilating apertures v12. These fluemembers support a deflector member 18 wh ch is provided with a pluralityof ventilatlng apertures 14. The deflector member 13, as will be seen bycarefully considering Fig. 1, will distribute the heat passing from thelaterally extending flue members 11 over a broad surface in view of thefact that the deflector 13 extends from one end of one member 11 to theopposite end of the adjacent member 11. By having the deflector member13 formed as illustrated, it will be seen that a considerable radiatingsurface has been produced whereby heat may be radiated from theabsorber. This deflector member 13 is formed with a plurality of rolledportions 15, and a second deflector member 16 is supported over theinner ends of the flue member 11 as indicated in Fig. 2. It will befurther seen that the deflector 16 will also constitute a wide heatradiating surface for spanning the junction of the laterally extendingflue with the vertically extending flue 6. A deflector plate 17 issupported above the lamp 4: and is suspended from the deflector member16 by means of a bolt 18. In this manner the heat rising from the lampwill strike the deflector plate 17 and be deflected up through the flue11. A closure plate 19 is carried by each flue 11 and this plate willprevent the heat from escaping from the ends of the flues, but will keepthe heat congested so as to have a good effect upon the instrumentwithin which the heater is carried.

From the foregoing description, it will be seen that a very eflicientand durable device has been produced which may be formed of sheet metal,and since it may be formed of sheet metal it will be seen that the samemay be very cheaply constructed. It will be further understood thatowing to the different passages through which the air passes that thesame will become very quickly heated to a greater intensity owing to thegreat amount of circulation which occurs therein.

Having thus described the invention, what is claimed as new, is

A device of the class described comprising a base provided with inwardlypunched supporting tongues, a lug supported on the outer face of saidbase, a vertically extending flue supported upon said base by means ofsaid lug, laterally extending fiues carried by said vertically extendingflue and secured thereto, a deflector member straddling said laterallyextending flues, a second deflector arranged over the junction of saidlaterally 15 extending fines and beneath said first mentioned deflector,each laterally extending flue provided With ventilating apertures formedin the upper face thereof, and a deflector plate suspended over saidvertically 19 extending flue from said last mentioned deflector forcausing heat formed Within said vertically extending flue to be radiatedto said laterally extending flues.

In testimony whereof We hereunto afiix our signatures in presence of twoWitnesses. 15
